Hi Uwe,
The following code is what I use. It uses filladapt mode, but doesn’t
work with auto-fill (I manually refill paragraphs with M-q as I’m
writing). I wrote the code a long time ago, it works for me, YMMV,
etc. Hope it is helpful.
#+BEGIN_SRC emacs-lisp
(defun awe-org-fill-paragraph-function (&rest ignore)
(let ((bounds (cons (save-excursion (backward-paragraph) (point))
(save-excursion (forward-paragraph) (point))))
beg end end-marker)
(save-excursion
(goto-char (cdr bounds))
(skip-chars-backward "\n")
(setq end-marker (point-marker))
(setq end (make-marker))
(goto-char (car bounds))
(skip-chars-forward "\n")
(catch 'exit
(while t
(setq beg (point))
(forward-sentence)
(move-marker end (point))
(save-excursion
(goto-char beg)
(when (and fill-prefix
(not (looking-at-p (regexp-quote fill-prefix))))
(insert fill-prefix))
(while (re-search-forward "\n *" end t)
(replace-match " ")))
(setq beg (point))
(skip-chars-forward " \n")
(move-marker end (point))
(when (>= (point) end-marker)
(throw 'exit t))
(when (/= beg end)
(delete-region beg end))
(insert "\n"))))
(set-marker end-marker nil)
(set-marker end nil)))
